Routing electrical

For routing low speed DC electrical ports you can use sharp corners instead of smooth bends.

You can also define port.orientation = None to ignore the port orientation for low speed DC ports.

Single route functions

get_route_electrical

Get route_electrical bend = wire_corner defaults to 90 degrees bend.
